The USS Seahorse (SS-304) was one of the top ranked submarines in the
Pacific during World War II. She completed eight impressive war patrols
under four different skippers, two of whom earned the coveted Navy Cross.
Her most successful CO was Commander Slade D. Cutter of Chicago, Illinois.
As Captain of the Seahorse, Cutter destroyed 19 enemy ships, placing him
second in the overall score for submarine commanders of WWII. In 1945,
at wars end, Seahorse ranked sixth in the number of ships destroyed and
twelfth in tonnage sunk. The book Maru Killer by
Dave Bouslog makes exclusive use of the submarine's war patrol reports
as well as extensive interviews and correspondence with her surviving officers
and enlisted men.
The USS Seahorse sank over 20 Japanese ships and even another Japanese
Submarine
The Seahorse was one of the most "fightin'est" Submarines of World
War II
and her second war patrol was probably her most succesful.

Three fishing trawlers were sunk by SS-304 gun attack

USS Seahorse sailed on 20 October for her second war patrol. She sank
three enemy trawlers in surface actions and then, along with the USS Trigger
commenced a two day attack on a 17 ship Japanese convoy. Seahorse evaded
three escort ships and fired three torpedos at two freighters. Four hours
later she again attacked, sending three more torpedos at a tanker and another
spread at a third freighter. Flames burst from each target as Japanese
destroyers turned towards Seahorse but they were too late to catch her.
Seahorse expended the last of her torpedos on 30 November. After manuevering
for several hours she was finally able to fire her stern tubes at the enemy
convoy. However, one torpedo exploded close aboard and the convoy opened
fire on the vicinity of Seahorse. With so many explosions around her, it
was impossible for her to determine whether any torpedos had hit. Low on
fuel and out of torpedos, she returned to Pearl Harbor.
